In allusion to future antiterrorism sensor network without communications infrastructure, limited bandwidth must be able to provide unlimited high transmission rate and low error rate, having explored for its information transmission technology. A new generation of mobile communications with the OFDM, MIMO, SA and other technologies was discussed. MIMO was the main design. MIMO combined with OFDM. QoS optimized spatial multiplexing and space diversity. From computer simulation with MATLAB, the choice of techn…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
